IMPROVEMBNTIN WELL-TUBES?? TO ALL WHDMIT :MAY C ONCERN: Be it known thatv I, i`W{T. ,HennE1i, .-oiitheeity of Bui'alo, in the county of Erie, and S-tate of New York, have invented acertain new and useful Improvement in Tube-Wells; andi do hereby declare that the followin g is a full and ezratrdescriptionthereof, r'eferencehbeing'had to theaecompanying drawings,'making' part of this specieation, in whichr 1 vFigure 1 is a vertical section ofthe lower portionof the tube in the ac t of being driven into the earth. Figure 2 is a section made in a plane at rightangles to that of iig. 1, showing the tube drawn up, so as to uncover the slits'and perferationsthrough which-the water enters.

Figure 3 is a. cross-section in linex', g. 2. v H I Figure 4, 'a similar section ofthe point in -planeof redline Like letters refer to like parts. i'

Myinvention consists in the construction of a Weil-tube with-an external section orshielding-tube conneeted with the drivinglpoint, and provi-ded with a xed cross-bar, which passes through vertical slots of the .inner tube, said slots being so constructe-dlas lto allow thev inner tube to be drawn upward a limited distance, to

uncover openings for the admissionof the water, and provided with lateral recesses, by means of which the inner tube'may bepartially turned within 'the "external one, whereby the said bar is caused to lock the two tubes together, securing them in the same relat'ive'position, thosaid bar acting at the same time as atransverse brace `audvstrengthene-r of the outer tube, and aiording-a means by which the point may b'e further driven into the earthV after the water-openings have been uncovered, or the p oint wholly withdrawn, if-required.

` 4In the drawings, A represents .the point-,-B the short outer tube or shield attached thereto, provided with fine slits dabrperforatens b, or both, as preferred, for the ingress of the water. C, the main tube of the well, the lower end A'of which fits se as .to 'slide within the tube B. The lower end ofthe tube C is provided with slots e e, through which passes a key, D, that is fastened transversely in lthe outer tube. vThese slots are se formed as to allow theitube C to slide down within the outer on'e,B, and close-the apertures a b in the latter during the process of driving, (as shown in iig. 1,) so as to exclude the dirt-and sand from entering the tube, and to permit it to be afterwards elevated, uncovering the apertures, as represented in fig. 2. A The lower ends ofthe slots e c are provided with ajog or recess, d, that'in the one being on the side opposite that on the other, so that by giving the tube C a slight turn'after it hasbeen raised, as above described, the key D will be brought in these recesses, and the tube sustained in that position. I

The point A,for penetrating the earth, is lformed with four' concave sides, z'z', as shown in cross-section in iigjl, which gives thecorners m m at'their junction a sharp edge, that enables the point te more readily penetrate the .earth than when made with the ordinary coniea'l point, or with the sides z'z'straight in cross-section instead of concave, as shown.

This form of the point also operates to prevent the shield ,or outer tube B, to which it is attached, from turning with the tube C in adjusting the key in the recesses d, as before described. The formation ofthe slot -in the inner tube C, connecting with the key D, enables the formerto be slid down so as to close the openings Y a b while the tube is being driven, andthereby prevent the sand and dustfrom being foreedthrough into the tube and to be afterwards raised, so as to uncover them, and .to be sustained inthat elevated position by the key D, fitting in the recesses CZ. v Were the slots c formed in the outer tube or shield B, instead of the inner one, the

clay or dirt would be so pressed and packed therein, during the driving of the tube, ns to render it at times impossible to raise the tube without at the same time raising the point or shield with it. My arrangement of tbe slet, as is readily perceived, overcomes this difficulty. I

do not claim broadly closing the apertures a b by means of' the tube C sliding within, but

The combination cf the outer tube B, provided with the ero`ss-bar D, with the inner tube C, provided'with the slots c c and recesses d d at the bottom thereof, constructed and arranged in the manner and for the purposes set forth.

In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.

W. T. HORNER.
